Apparently, the embodiments described below are a part, but not all, of the embodiments of the present invention. Generally, a component, described and illustrated in the accompanying drawings, in the embodiments of the present invention may be disposed and designed in various different configurations.

All of the other embodiments, obtained by those skilled in the art based on the embodiments of the present invention without any inventive efforts, fall into the protection scope of the present invention.

Referring to FIG. 1, an embodiment of the present invention provides a gas meter fault prompting method based on a compound IoT, which is applied to a gas meter fault prompting IoT system based on the compound IoT. The gas meter fault prompting IoT system based on the compound IoT includes a plurality of user sub-platforms 500, a service platform 400, a management platform 300, a plurality of sensor network sub-platforms 200 and a plurality of object sub-platforms 100. Herein, any one of the plurality of object sub-platforms 100 may be communicatively connected with the management platform 300 via any one or more of the plurality of sensor network sub-platforms 200, so as to send data of the object sub-platform 100 to the management platform 300, or receive a signal sent by the management platform 300. The management platform 300 is communicatively connected with the service platform 400. In this embodiment, the service platform 400 may include at least one of a gas company service platform 400, a government service platform 400 or a social operator service platform 400. The service platform 400 is communicatively connected with the user sub-platforms 500, and is configured to receive information sent by the user sub-platforms 500 and forward the information to the management platform 300, as well as push information sent by the management platform 300 to the user sub-platforms 500. The management platform 300 and the service platform 400 each may be a server. Each of the object sub-platforms 100 includes a gas meter. As shown in FIG. 2, the gas meter fault prompting method based on the compound IoT may include the following steps.

Step S201: Each of gas meters checks own operation state information in real time for a fault, and in case of a fault, step S202 is executed.

Step S202: The gas meter sends the operation state information to the management platform 300 via a corresponding sensor network sub-platform 200.

In this embodiment, the plurality of sensor network sub-platforms 200 may be a plurality of different gateways, and each of the object sub-platforms 100 sends information to the management platform 300 via one or more gateways. The management platform 300 communicates with the gas meters via the sensor network sub-platforms 200 so as to receive operation state information in real time. Herein, the information can be sent once every 1 min, 5 min or 10 min, and preferably once every 1 min to the management platform 300.

Step S203: The management platform 300 inquires the fault type and solution according to the operation state information and preset fault inquiry table.

Specifically, for example, the fault type inquired by the management platform 300 according to the operation state information and preset fault inquiry table is that a battery capacity is insufficient, and the inquired fault solution is to replace a battery.

For another example, the fault type inquired by the management platform 300 according to the operation state information and preset fault inquiry table is that positive and negative electrodes of the battery of the gas meter are in poor contact, and the inquired fault solution is to clean the battery and wipe the aluminum sheet and spring in the battery box.

In addition, common fault types of the gas meter further include arrearage, gas leakage and the like, and the management platform 300 may inquire a solution respectively via the preset fault inquiry table, which will not be repeated herein.

Step S204: The management platform 300 sends the fault type and solution to the service platform 400.

Step S205: The service platform 400 sends the fault type and solution to a corresponding user sub-platform 500 to display.

In this embodiment, each of the user sub-platforms 500 may be a universal electronic device, such as a Personal Computer (PC), smartphone, tablet computer, Personal Digital Assistant (PDA), and Mobile Internet Device (MID). A user can look up the fault type and solution of the gas meter at the user sub-platform 500, and completes corresponding repair processing independently.

Besides, in this embodiment, if a specific fault type occurs for multiple times, such as gas leakage, and excessive gear abrasion, the gas meter cannot be used any more, and it is necessary to remind the user of replacing the gas meter. Therefore, as shown in FIG. 3, after step S203, the gas meter fault prompting method based on the compound IoT may further include the following steps.

Step S206: The management platform 300 judges whether or not the fault type is a specific fault type according to the operation state information, and if yes, step S207 is executed.

Step S207: The management platform 300 judges whether or not the number of times that the fault of the specific fault type occurs in the gas meter exceeds the preset number of times, and if yes, step S208 is executed.

The preset number of times varies due to different fault types, and the specific number of times is determined based on the fault type.

Step S208: The management platform 300 generates a gas meter replacement prompt, and sends the prompt to a corresponding user sub-platform 500 via the service platform 400 to display.

The user can look up the gas meter replacement prompt at the user sub-platform 500 and replace the gas meter independently.

Additionally, in this embodiment, the fault type is associated with gas fee information and thus it is possible that the final calculated gas fee is unfair to the user, if the fault type is gas leakage or excessive gas injection or inaccurate counting. In this sense, the gas fee needs to be recalculated. Therefore, as shown in FIG. 4, after step S202, the gas meter fault prompting method based on the compound IoT may further include the following steps.

Step S209: The management platform 300 judges whether or not the fault type is associated with gas fee information, and if yes, step S210 is executed.

Step S210: The management platform 300 acquires a gas consumption history record within a preset time from the gas meter corresponding to the fault type.

Step S211: The management platform 300 calculates an average value of monthly gas consumption within the preset time according to the gas consumption history record, and takes the average value as current month gas count data to calculate current month gas fee information.

In this embodiment, the fault type is associated with the gas fee information, which refers to that gas count data in the last month mismatches with gas data used by the user in the current month due to the fault of the gas meter, e.g., the count of the gas meter is excessively large and is in inconformity with an actual use condition due to the gas leakage, so in order that gas data in the month when the fault occurs in the gas meter is in conformity with the actual use condition approximately, the average value of monthly gas consumption is taken as the current month gas count data. For example, if the current month is July, the average value of monthly gas consumption in the first half year (i.e., January to June) is calculated, and the average value is taken as the current month gas count data, thereby being relatively reasonable.

Step S212: The management platform 300 sends the current month gas fee information to a corresponding user sub-platform 500 via the service platform 400 to display.

Referring to FIG. 1, an embodiment of the present invention further provides a gas meter fault prompting IoT system based on a compound IoT. It is to be noted that for the gas meter fault prompting IoT system based on the compound IoT provided by this embodiment of the present invention, the basic principles and generated technical effects are the same as the those of the foregoing embodiment.

In addition, in this embodiment, the management platform 300 is further configured to judge whether or not the fault type is a specific fault type according to the operation state information.

If the fault type is the specific fault type, the management platform 300 is further configured to judge whether or not the number of times that the fault of the specific fault type occurs in the gas meter exceeds the preset number of times.

If the number of times that the fault of the specific fault type occurs in the gas meter exceeds the preset number of times, the management platform 300 is further configured to generate a gas meter replacement prompt, and send the prompt to a corresponding user sub-platform 500 via the service platform 400 to display.

Besides, in this embodiment, the management platform 300 is further configured to judge whether or not the fault type is associated with gas fee information.

If the fault type is associated with the gas fee information, the management platform 300 is further configured to acquire a gas consumption history record within a preset time from the gas meter corresponding to the fault type.

The management platform 300 is further configured to calculate an average value of monthly gas consumption within the preset time according to the gas consumption history record, and take the average value as current month gas count data to calculate current month gas fee information.

The management platform 300 is further configured to send the current month gas fee information to a corresponding user sub-platform 500 via the service platform 400 to display.

In conclusion, according to the gas meter fault prompting method and IoT system based on the compound IoT, each of the object sub-platforms is configured to check the own operation state information in real time for a fault; the management platform is configured to inquire the fault type and solution according to the operation state information and preset fault inquiry table, and send the fault type and solution to the corresponding user sub-platform via the service platform to display, so that the user can know and view the fault type and solution of the gas meter at the user sub-platform in a timely manner and thus may repair some simple faults of the gas meter independently; the invitation for a person of a gas company to the site for handling turns out to be unnecessary; and therefore, the time cost and the labor cost are saved.
